Case Demonstration: Assessing Two Cases with the ETIVB-Instrument
In this the researcher will demonstrate the use of the ETIVB-Instrument by showing how it has been applied to two study cases, namely Sanders and Jacaranda 94.2 and S v Campher. The reader may refer to précis of the two study cases in Addendum C to Chapter 14. The précis in Addendum A to Chapter 14 are the same précis that have been used by study participants. The researcher however, has had a copy of the original court verdict as reported in criminal law reports at his disposal. The reason for rating criteria will be discussed for both Sanders and Jacaranda 94.2 and S v Campher. This will be done in order of the sequence they appear on the ETIVB-instrument.
The reasons for choosing these two study cases are that 1) Sanders and Jacaranda 94.2 is the only example of a case study where the requirements of „ETIVB‟ are satisfied; 2) S v Campher is an example of a challenging case where the requirements of „ETIVB‟ are not satisfied, as evidenced by the Supreme Court of Appeal not having reached a unanimous decision; 3) both cases have enough information for the purposes of applying the ETIVB-Instrument to them. Starting with Sanders and Jacaranda 94.2 the researcher will demonstrate how the ETIVB-Instrument and Attributive Considerations of ETIVB have been used, and following that, how the ETIVB-Instrument (without the Attributive Considerations of ETIVB) was used in S v Campher.
Construct Validity of the ETIVB-Instrument
Construct validity refers to whether the measure correlates, quantitatively or conceptually, with external validators and is based on convergent and divergent validity.127 Convergent validity in quantitative terms refers to the expected loading of the items from the construct under study on the same factors from measures of similar constructs.127 conceptually, convergent validity is about sufficient similarity between concepts. Accordingly, the ETIVB-Instrument has convergent validity insofar as it converges with court verdicts. Divergent validity (also called discriminant validity128 in qualitative terms is the expected loading of the items from the construct under study on the different factors from measures of different constructs.127 Conceptually, divergent validity is about the distinctness of the concept from other related concepts. Construct validity turns out to be a useful external validator for assessing the validity of the ETIVBInstrument. Blacker and Endicott describe external validators (for external validity) as follows, “External validators are attributes that bear a well-characterized relationship to the construct under study, but are „beyond the score‟ (i.e., are not measured directly by the instrument).127 In the context of this study such an external validator (although as will be seen not perfect) turns out to be court verdicts (guilty or not guilty).
